of electron emission by no-corona electrode was introduced into the process of NO removal by ammonia-based selective no-catalytic reduction (SNCR), and the reaction mechanism was analyzed. The influence... discharge; selective no-catalytic reduction; NO NO为燃煤锅炉烟气主要污染物,目前燃煤锅炉脱除烟气NO的方式主要有选择性催化还原技术(SCR)和选择性非催化还原技术(SNCR).SNCR脱硝技术相对SCR法投资运行成本较低,但通常煤粉炉仅能达到30%左右的脱硝效率,循环流化床锅炉在良好工况下可以达到50%左右的脱硝率[1-2],其脱硝效率相对较低的缺点一直限制着其大......
NO catalytic activity of selective catalytic reduction with ammonia (NH3) by CuMn-ZSM-5 catalysts HUANG Xiu-guo, LI Cai-ting, LU Pei, LI Qun, DING Yan-min (College of Environmental Science & Engineering, Hunan University, Changsha 410082, China) Abstracts: CuMn-ZSM-5 catalysts were prepared by incipient impregnation method, and NO catalytic activity of selective catalytic reduction (SCR......
membrane fuel cells (PEMFCs) by 10% within 100 h [4]. The exposure to 5×10–6 NO2 for 12 h could lead to 55% loss on the current of PEMFCs [5]. NOx (NO: NO2=9:1) of 140×10–6 could cause a 30% reduction... vehicles in a long term. Although selective catalytic reduction (SCR) of NOx with NH3 is effective at relatively high temperatures [7, 8], NOx removal by sorbents like activated carbons (ACs) is still......
